What is Benzene?
BENZENE (pronounced ben zeen)
Chemical Formula: C 6 H 6
Chemical Abstract Number (CAS#): 71-43-2
Other names: Benzol, Coal Naptha, Phenyl Hydride
Benzene is a clear, colorless, non-corrosive, highly flammable liquid with a strong odor. It is used primarily to make other chemicals and plastics. It is commonly found in solvents, degreasers, in the dye, dry cleaning and petroleum industry. It has also been an ingredient in some commercial products including dental/denture adhesives and cigarettes.
Benzene is even a component of cigarette smoke. Benzene is widely used in the United States and ranks among the top 20 chemicals produced. EPA classifies benzene as "a known carcinogen" (Group A) (EPA, 1996). Benzene related diseases may develop as late as 29 years after exposure.
We knew benzene caused disease as early as 1897 when doctors linked it as a cause of aplastic anemia. Now we know it causes more than that. One hundred years later, in 1997, the report to the Canadian Occupational Board on Occupational Diseases summarized links between benzene and diseases:
Gasoline distribution workers, laborers, pipe fitters and refinery workers others involved in the removal and repair of underground fuel storage tanks and refinery workers are at risk for exposure to benzene.
Benzene is absorbed predominately through inhalation of benzene vapors. Benzene can also be absorbed through skin.
Consumer products . Some consumer household products, such as glues, cleaning products, detergents, art supplies, and paint strippers, contain benzene.
Benzene Effects
The evidence linking benzene and cancer predominantly comes from studies of workers, and relates to leukemia, particularly a type called acute myeloid leukemia (AML). Leukemia is a cancer of blood-forming cells in the bone marrow. Benzene exposure is related to many forms of leukemia:
AML (acute myelogenous leukemia)
ALL (acute lymphatic leukemia)
CML (chronic myelogenous leukemia)
CLL (chronic lymphatic leukemia)
Hodgkin's Disease
HCL (hairy cell leukemia)
Aplastic anemia (a risk factor in developing acute nonlymphocytic leukemia)
These versions of Leukemia are not:
Non-Hodgkin's Lymphoma
Multiple Myeloma.
Some benzene health effects, such as central nervous system toxicity, can occur immediately after or shortly after benzene exposure. Benzene has been known to cause acute myelogenous leukemia, acute lymphocytic leukemia, chronic myelogenous leukemia, chronic lymphocytic leukemia, non-Hodgkin lymphoma and aplastic anemia.
The U.S. Department of Health and Human Services and IARC have determined benzene is a known human carcinogen.
Symptoms
Symptoms of the disease are very similar to the flu or other common diseases symptoms often include:
- Fatigue
- Malaise (vague feeling of bodily discomfort)
- Abnormal bleeding
- Excessive bruising
- Weakness
- Reduced exercise tolerance
- Weight loss
- Bone or joint pain
- Infection and fever
- Abdominal pain or "fullness"
- Enlarged spleen, lymph nodes, and liver
A blood test can be used to check for a specific blood abnormality. If you are experiencing some or most of these symptoms, you should discuss them with your doctor who may suggest diagnostic tests.
What
Should I do if I suspect that I may have
Benzene?
If you have evidence of Benzene disease,
you may be entitled to compensation for
your illness. The laws involve a statute
of limitations, or time limit, to file a
claim. We recommend that you talk to an
attorney about your situation.
